Identify vendor lock-in early and assess its economic impact.
Vendor lock-in can be measured by data export, switching costs, contract commitment, and replacement options. This allows exit risks to be clearly incorporated into the system selection.
For management and product managers, the economic evaluation of vendor lock-in can be examined using three specific criteria: "Complete Portability," "Replaceable Operating Method," and "Sham Issue."

How can vendor lock-in be economically evaluated before a platform decision?
Vendor lock-in is assessed based on specific switching barriers: data export, contract terms, replacement integration, knowledge loss, and business interruption. Each barrier requires a realistic exit strategy with associated effort and responsibility. Only a comparison with the expected benefits reveals whether the vendor lock-in is justifiable.
Complete portability
Complete portability Not only tables, but also relationships, files, status histories, and necessary metadata must be extractable in documented form.
Detachable operating path Authentication, interfaces, and automations require a designated alternative that can be executed without the involvement of the previous vendor.
Contractual Flexibility – Termination windows, data access after contract end, and exit support services must align with the technical migration timeline.
Sham Export
Sham Export – A formal export exists but does not provide a model from which the ongoing process can be restored.
– The migration path is only evaluated in the event of a conflict and then encounters time pressure, a lack of knowledge, and expired access. ... – Training, special processes, and manual workarounds tie up the organization more than the software itself.
Unverified Exit Costs – The migration path is only evaluated in the event of a conflict and then encounters time pressure, a lack of knowledge, and expired access.
Detachable operating path
Capture all business-critical data objects and dependent processes in an exit inventory.
Transfer a complete export with real-world links into a vendor-neutral test structure.
Evaluate technical, contractual, and organizational migration costs together with the expected platform benefits.
Contractual Flexibility
Determine the proportion of critical data objects that, along with their relationships, can be restored for testing purposes.
Estimated duration observed during the trial run until a functional replacement process is in place.
Implementation scenario: "Sham output"
A system exports master data as CSV but maintains process history and file links in an undocumented format. The nominal export is therefore insufficient: A test import into a neutral target structure reveals which information would be lost and what rework a change would trigger.

Conclusion: Economically Evaluating Vendor Lock-in
Lock-in is economically viable if its benefits outweigh the documented exit costs and a feasible switching path is maintained. Without testing, data portability remains merely a contractual claim.

Key Thesis
Vendor lock-in is not a gut feeling, but rather the sum of technical, contractual, and organizational switching barriers. Costs, duration, and realistic decommissioning options are evaluated.
What This Is Not About
Vendor lock-in cannot be deduced from the number of proprietary functions or from a general aversion to vendors. Standard software is not automatically an economic trap either.
What it's about
The crucial factor is how complex it actually is to migrate and reuse data, processes, and knowledge during a switch. These exit costs must be included in the investment calculation before committing to a vendor.

Full Portability: Practical Implications
Before committing to a long-term vendor, a joint exit test with technology, procurement, and process owners is worthwhile. An independent system audit can translate the remaining obstacles into a sound decision.
